Fair enough, but running a larger table on the -union- data still poses no
problem on my machine (save the (minor?) error registered at the end):

....

         Pearson chi2(11) = 107.8144   Pr = 0.000
likelihood-ratio chi2(11) = 105.0420   Pr = 0.000
               Cram�r's V =   0.0641
                    gamma =   0.0342  ASE = 0.009
          Kendall's tau-b =   0.0192  ASE = 0.005
integer overflow due to large row margin frequencies
r(1401);
Yes, but notice, you never got Fisher's exact test reported!
